Proxmox Hypervisor Restarts itself

[orlipr84]

Hi friends, if you can help me to detect the problem, I would greatly appreciate it. First of all, I do not speak English, I am using Google Translate to be able to publish my issue in this wonderful forum, I hope you understand me and I apologize for writing and understanding errors.

Problem:

I have three Fujitsu PRIMERGY RX2540 M6 servers running Proxmox 8.1.3 in a cluster and randomly the servers reboot itself.

Can you help me with any guide or steps to detect the issue?

Thank you for your support.

Hi,

I have three Fujitsu PRIMERGY RX2540 M6 servers running Proxmox 8.1.3 in a cluster

As suggest, I would upgrade the Proxmox VE nodes to the latest available version.

and randomly the servers reboot itself.

Have you checked the syslog at the server reboot time? You can get the syslog with specific time/date using journalctl e.g.:

journalctl --since "2024-07-16 01:00" --until "2024-07-17 15:00" > /tmp/$(hostname)-Syslog.txt

You may edit the date/time in the above command.

High latency on HDD based Ceph OSDs is usually a result of the random write penalty. Ceph is designed for parallel throughput, but spinning disks fall apart when forced to handle the tiny, random metadata writes required for objects. NVME is the solution but if you can't upgrade the storage try moving your cold data to an archive to reduce the size of the load.

Any way we can get a pvereport output?
